, An object of this invention is to provide an improved pulverizing millor mechanism by means of which various kinds of material may be fed intothe mill at the desired rate of speed.

A further object of this invention is to provide an improved pulverizingmechanism by means of which the pulverizing wheel is rotatably mountedwithin the housing so that the material may be fed into the housing fromone side thereof.

A still further object of this invention is to provide a chute which maybe mounted on a pulverizing mechanism of this kind, the chute embodyingmeans for feeding a predetermined quantity of material into thepulverizing mechanism.

The above and various other objects and advantages of this inventionwill in part be described in and in part be understood from thefollowing detailed description of the present preferred embodiment, thesame being illustrated in the accompanying drawings, wherein Figure 1 isa detail side elevation partly broken away of a device constructedaccord ing to the preferred embodiment of this invention;

Figure 2 is a fragmentary sectional view partly in detail taken on theline 22 of Figure 1;

Figure 3 is a sectional view taken on the line 33 of Figure 1;

Figure 4 is a fragmentary longitudinal section taken substantiallythrough the loni gitudinal center of the chute, and

mounted on the upper ends thereof. A pulley 15 is mounted on the shaft12 intermediate the standards 14 and a flexible member in the form of abelt or the like, may be trained over this pulley 15, so as to rotatethe pulverizing member 11. This housing 10 is provided with an intakeport 16 at one side thereof and substantially concentrically of theshaft 12 and disposed about this intake port 16 is positioned afrusto-conical intake spout'17 which has a flange 18 secured to the sidewall ofthe housing 10 by means of bolts 19 or the like. i I An elongatedchute, generally designated as 20, is secured to the spout 17 andextends at an upward inclination therefrom, the inner end portion 21 ofthe chute being curved so as to substantially conform to theconfiguration of the frusto-conical spout 17, and the outer end of the.chute 20 is bent in substantially U-shaped form, as disclosed in Fig ure3, having a fiat bottom 22 and vertically disposed side members 23. Thischute 20 is securely held in upwardly inclined position by means of apair of bracing members 24, which are preferably of channel or angularconstruction, being secured at one end to the housing 10 by means ofbolts 25 and secured to the chute 20 by means of bolts 26 or the like.The material which it is desired to pulverize or grind in the housing 10is fed into'the housing by means of the chute 20, and in order tocontrol the amount of material passing downwardly within the chute 20, Ihave provided a closure member, gener- 'ally designated as 27 which ishinged, as at 28, to the spout or intake member 17.

This closure member 27 comprises an upper plate 29 which is hingedto'the intake member 17 and a lower plate 30 which is pivotally 9secured adjacent one edge thereof to the upper plate 19 by means of apivotal member 31. These plate members 29 and 30 are constructedsubstantially in the form of a semicircular plate which overlap eachother at the abutting edges thereof, and the lower plate 30 is providedwith a segmental slot 32 for receiving a bolt 33 which is carried by theupper plate 29, and a thumb nut 34 is threadably mounted on the bolt 33and is adapted V prisi to hold the lower plate 30 in vertically adjustedposition with respect to the upper plate 29. a

When the lower plate 30 is lowered, the peripheral edge thereof isadapted to enga the inner surface of the lower end of t e chute v2f.) seas to close this opening and prevent the passage of material into thehousi from the chute 20. As disclosed in dotte lines in Figure 2, thelower plate may be raised upwardly so as to permit material to passtherebeneath and into the housing 10, or if desired, the entire closure27 maybe swung upwardly on the hinge 28 so as not to impede the passageof the material, such as he straw or the like passing downwar y throu hthe chute 29 and the intake member 17. #J. 's upper plate 29. isprovided with a plurality of apertures therethsrough, so as to permltthe entrance of air or the like into thehousing and to prevent theformation of a vacuum within the housing 10 as the materialrnassesthrough the intake port 16.

IILthe operation of this device, the pull l5 and the shaft 12 areadapted to be rotate from a conventional power member so as to rotatethe pulverizing member 11,rthe operation of which is more specificallydescribed in my prior patent hereinbefore referred to. The closure 27may be opened to the desired degree, depending upon the character of thematerial which it is desired to pulverize.

It is, of course, understood that various changes and modifications maybe made in the details of construction and design of the abovespecifically described embodiment of invention without departin from thespirit thereof, such chan es an modifica- I tions being restricted onlyhy the scope of the following claims.

I claim I 1. In a pulverizin means, a frustro-conical intake member, ana closure engaging the outer end 05 the member, said closure coman upperrtion swingable outwardly of e outer en of the member, and a loworportion swingable transversely of the outer end of the member.

2. In a pulverizing means, an intake member, a closure for said memberand hinge means forhinging the closure to the member for upward swingingmovement, said closure comprising an upper plate, a lower plate, a pivotfor securing the lower plate to the per plate for vertical swingingmovement in a plane parallel to the outer surface of the upperflate, andmeans engaging each plate to hol the lower plate in ad usted osltion.

3. In a pulverizing means, an inta e memcenter thereof, one of saidplates having an arcuate slot therein, and a thumb bolt carried by theother plate and extendin through the slot whereby to permit verticaadjustment of the lower plate relative to the upper plate.
